Drivability and Fuel Economy Evaluation of a Sport Utility Vehicle Using CAE Tool

Abstract:

To establish accurate models for powertrain optimization of a Chinese sport utility vehicle Landwind X8, a powerful CAE tool GT-Drive was used to evaluate the vehicle drivability and fuel economy. Various proper models were established and vehicle performance was simulated, obtained results show that drivability of the vehicle is satisfactory in a macro sense, but fuel economy is moderate. Further comparison of simulated performance indices with field test data demonstrates that nearly 80% of the absolute relative errors are below 5%, the maximum absolute relative error is also less than 10%. Thus, the simulated data met well with the test data, it is confirmed that the established simulation models are validated and can be used as effective analysis tools in further powertrain optimization.
